We already have a large flock of chickens, and we'd like to start raising ducks as well. We live on a river, and have a large shallow natural pool that's fed and filtered by the river. I'm planning to house the ducks separately from my chickens. I'd like to have 3 or 4 ducks. So my question is...which breed? I'd like to hatch the eggs. Are some breeds easier to hatch than others? Which breeds are quieter? Could it be a problem that we have wild ducks that come through seasonally?
